The thesis presents an approximation procedure for dimensioning and design of composite columns based on the simplified design method of Eurocode 4. The ultimate load of a composite column is determined as the product of the total area with an effective stress. Buckling safety is provided by using the slenderness ratio L/R instead of the non-dimensional slenderness, L being the length of the column and R its effective radius of gyration. Furthermore, numerous means are provided to calculate the effective radius of gyration of a composite column by multiplying the radius of the steel section with a correction factor. The procedure can be used both in university education of architecture and by structural engineers for dimensioning and design of composite columns. In many cases, approximately calculated ultimate column loads are equal to those calculated by Eurocode 4 method. Design of fire-resistance is also possible.
